The sliding part is slidably mounted on the base frame along the front-to-rear direction and abuts against the back of the button body under the elasticity of an elastic part which is flexibly disposed between the sliding part and the base frame. A guide pillar is protruded at a position of the rotating part away from the rotation axis. The rotating part is rotatably mounted to the rear of the base frame through the rotation axis thereof being pivoted to the centre of a circle of the guide slot. The rotating part is parallelly rotatable between the base frame and the circuit board. The guide pillar passes through the guide slot to be slidably inserted in the guide channel of the sliding part. In use, the sliding part can slide on the base frame along the front-to-rear direction by virtue of the push of the button body and the elastic part, the sliding of the sliding part can drive the guide pillar to slide rearward and forward along the guide slot under the cooperation of the guide slot and the guide channel and further drive the rotating part to rotate with respect to the circuit board, and the rotation of the rotating part further drives the electronic components to electrically connect with or disconnect from the circuit board.

As described above, the button structure in this invention utilizes the cooperation of the button body, the base frame, the sliding part, the elastic part and the rotating part to convert the actions in different directions (namely converting the action of pushing the button body along the front-to-rear direction into the rotation of the rotating part in a direction parallel to the circuit board), so as to achieve the electrical connection and disconnection of the electronic components fixed on the rotating part and the circuit board disposed in the game controller. In general, the button structure used in the game controller can utilize the cooperation action of machinery to coordinate the actions in the different directions easily.

The button body 10 is assembled in a front face of the game controller 100 and shows a cover shape with a middle portion being arched forward and brim all around being tilted rearward. The inner side of the button body 10 defines a plurality of pushing portions 11. The pivotal arms 30 have front ends thereof fixed to two ends of the button body 10, and rear ends thereof define a pair of pivot shafts 31.

The base frame 20 is substantially of board shape and horizontally fixed in the game controller 100, wherein the base frame 20 is parallel over the circuit board 90 and located behind the button body 10. A pair of connecting arms 21 is protruded at two sides of a front end of the base frame 20, with a pair of pivot portions 211 being formed thereon respectively. The button body 10 is further pivoted to the front end of the base frame 20 by virtue of the cooperation of the pivot shafts 31 of the pivotal arms 30 and the pivot portions 211 of the connecting arms 21. A pair of restraining blocks 22 is protruded at two sides of a substantial middle of a surface of the base frame 20 opposite to the circuit board 90, and bent towards each other to define a sliding path 23 between the base frame 20 and the restraining blocks 22. A rear of the base frame 20 defines an arc-shaped guide slot 24 extending along a front-to-rear direction and located in rear of the sliding path 23. A hole 25 is opened in the rear of the base frame 20 and specifically at the centre of a circle of the guide slot 24. The substantial middle of the surface of the base frame 20 opposite to the circuit board 90 protrudes to form a wall 26 in front of the sliding path 23. A front face of the wall 26 protrudes forward to form a positioning pillar 27.

The sliding part 40 has a front board 42 placed vertically, two side boards 43 perpendicularly connecting with two ends of the front board 42, and a rear board 41 horizontally connecting between bottom edges of rear ends of the side boards 43. Accordingly, a window 45 is surrounded among the front board 42, the side boards 43 and the rear board 41. A guide channel 44 is transversely opened in the rear board 41, and a rear face of the front board 42 is concaved forward to form a receiving groove 46. The sliding part 40 is slidably mounted on the base frame 20 along the front-to-rear direction, and abuts against the back of the button body 10 under the elasticity of the elastic part 60, wherein the elastic part 60 is flexibly disposed between the sliding part 40 and the base frame 20. In detail, the sliding part 40 is slidably disposed in the sliding path 23 by means of the restraint of the restraining blocks 22 with the wall 26 of the base frame 20 being located in the window 45 of the sliding part 40; the elastic part 60 is flexibly clamped between the front board 42 and the wall 26 to keep the front board 42 against the pushing portions 11 of the button body 10. In this embodiment, the elastic part 60 is a spring of which one end is positioned in the receiving groove 46 of the front board 42 and the other end is sleeved around the positioning pillar 27 of the wall 26.

The rotating part 50 is rotatably mounted to the rear of the base frame 20 through the rotation axis 52 thereof being pivoted to the centre of the circle of the guide slot 24, and is parallelly rotatable between the base frame 20 and the circuit board 90. The rotating part 50 has a disc-shaped base board 51 of which the center perpendicularly protrudes to form the rotation axis 52. The base board 51 further perpendicularly protrudes towards the same direction as the rotation axis 52 to form a guide pillar 53 at a substantial edge away from the rotation axis 52. In detail, the rotation axis 52 of the rotating part 50 is pivoted to the hole 25 of the base frame 20, and the guide pillar 53 passes through the guide slot 24 to be slidably inserted in the guide channel 44 of the sliding part 40.

Referring to FIG. 2 and FIG. 4, in use, the sliding part 40 can slide on the base frame 20 along the front-to-rear direction by virtue of the push of the button body 10 and the elastic part 60. The sliding of the sliding part 40 can drive the guide pillar 53 to slide rearward and forward along the guide slot 24 under the cooperation of the guide slot 24 and the guide channel 44 and further drive the rotating part 50 to rotate with respect to the circuit board 90.
